Expose and Assess the Sewer Line Problem The depth at which you reach the sewer line will vary. It can be as shallow as 18 to 30 inches or as much as 5 or 6 feet. In cold climates, the pipe will be buried deeper to prevent the pipe from freezing in the winter. But pipe depth is not always a matter of climate.Click to see full answer. Also, how far down are sewer lines?The depth at which you reach the sewer line will vary. It can be as shallow as 18 to 30 inches or as much as 5 or 6 feet. In cold climates, the pipe will be buried deeper to prevent the pipe from freezing in the winter.Secondly, how deep are sewer pipes buried Australia? That’s a 225mm diameter pipe, probably a trunk joining a number of houses to the main. It should be quite deep, maybe a meter or more. The 150mm sewer pipe from the house to the 225mm would be at around 600mm depth (over the pipe). Likewise, how deep should water line be buried? The classic rule-of-thumb procedure for avoiding cold-weather damage to water pipe is “bury it deep.” If water lines are located below the lowest level of frost penetration—five to six feet or more in many cold region locales—they should be safe from freezing.How do you find a water line underground? You can find underground water pipes in your front or back yard in a very specific way. Purchase a pipe locator device that is capable of finding both metal and plastic pipes. Set up your pipe locator as directed. Walk through your yard, aiming the sensor on the pipe locator at the ground as you walk.
